BUTTON OR STUD.

SPECIFICATION forming part of Letters Patent No.339.15l, dated April 6, 1886.

Serial No. 196,295. (No model.)

To all whom it may concern:

Be it known that I, HENRY H. (loans, of North Attleborough, in the county of Bristol and State of Massachusetts, have invented a new and useful Improvement in Buttons and Studs; and I do hereby declare the following specification, taken in connection with the ac companying drawings, forming a part of the same, to be a description thereof.

This invention consists in a button or stud, to the head of which are attached, side by side, two L-shaped arms, one of which is adapted to be rotated axially, and is provided on its inner end with a tooth for engaging a locking spring or springs, the said head or the springs being furnished with a stop or stops to limit the movement of the said arm, as will be hereinafter set forth and claimed.

In the accompanying drawings, Figure 1 represents a rear view of a sleeve'button einbod ying the invention, with the arms in position for the button to be applied and removed. Fig. 2 shows the same with the arms in position to hold the button in place. Fig. 3 represents a vertical section of the button on line an 00. Fig. at shows a horizontal section of the button through the line y y of Fig. 3, with stops on the spring to limit the movement of the rotating arm. Fig. 5 shows a similar view with such stops located upon the back member of the button-head. Fig. 6 shows a top view of the back plate detached. Fig. 7 shows a plan of the spring detached. Fig. 8 repre' sents the arms detached and in perspective.

A is the button-head, which may be of any preferred form or style.

B B are the L-shaped arms, which, as shown in Figs. 1 and 2, are located side by side. The arm Bis preferably secured to the back plate, A, of the head by being passed through a hole, a, Figs. 3 and 6, and then riveted; but it may be attached to the head in any desired manner. The inner end of the arm B passes through a hole or bearing, a, Figs. 3 and 6, in the back plate, A, and is provided on its inner end with a tooth or plate, I), preferably riveted thereon. The arm B is rigidly attached to the head, and the arm B is adapted to be turned axially thereon. The tooth or plate b is shown as egg shape, but it may be triangular, rectangular, or of other proper form, as will be readily understood.

0 is the locking-spring, which is held in the head in any desired manner. As shown .in Fig. 7, the spring is preferably provided with a hole, 0, through which the inner end of the arm B passes, and is secured to the head by heading said end of the arm over upon it. To guard against the spring turning by any possibility on the end of the arm B, the spring is preferably furnished with a notch, c, which is occupied by a spur, a", on the button-back A, as shown in Figs. 4 and 5. The free ends of the spring 0 are bentinwardly, as shown in Figs. 4 and 5, so as to engage the tooth band lock the arm B in its two positions, and stops 0 c are preferably provided on the spring to limit the movements of the tooth b, and consequentl y of the arm B, to which it is attached. If desired, the stop 0 may be omitted, as the arm B, when swung to the position shown in Fig. 1, will engage the free end of the arm B, and thereby have its movement in that direction limited. In place, also, of locating the stops 0 c 011 the spring 0, they maybe spurs projecting from the back plate, as shown in Fig. 5, the spur 0 being omitted, if desired, for the reason just stated.

The operation of applying and removing the button and the action of the parts is as follows: Supposing the arms B B to be in the position shown in Fig. l, the tooth or plate I) will be in the position shown by full lines in Fig. 4 and by dotted lines in Fig. 5, the arm B being locked by the engagement of the spring 0 with said tooth or plate. The arms are now passed through the button-holes, and the arm B is rotated into the position shown in Fig. 2, bringing the tooth or plate b into contact with the stop 0", which limits the movement of said arm, and the arm will be locked insuch position by the engagement of the spring 0 with said tooth or plate, as shown by full lines in Fig. 5 and dotted lines in Fig. 4. Toremove the button the arm B is rotated from the position shown in Fig. 2 to that shown in Fig. 1, when the arms may be easily withdrawn from the button-holes. Vhen the arms B B, the spring 0, and the tooth or plate I) are secured by riveting, as described, the use of :00

solder in attaching these parts is avoided, and

a strong and durable button is the result.

Although I have shown a single spring, G,

for locking the arm B in position in order to secured to the head.

What I claim, and desire to secure by Letters Patent, is-

1. In a button or stud, the combination, with the head, of two L-Shaped arms attached thereto, side by side, one of which is adapted to be revolved axially, a locking tooth or plate secured to the inner end of the latter arm, alocking spring or springs located in the head for engaging said tooth or plate and locking the said movable arm, as described, and a stop or stops for limiting the movement of said arm, substantially as set forth.

' 2. The combination, with the head, of the L-shaped arms B 13, arranged side by side thereon, the former arm rigidly secured to the head and the latter arm mounted to revolve axially thereon, the tooth or plate 5, secured to the arm B, and a spring, 0, provided with a stop or stops for limiting the movement of said tooth or plate and locking the arm B in position, substantially as set forth.

3. The combination, with the head, of the L-shaped arms B B, arranged side by side thereon, the former riveted to the head and the latter mounted to revolve axially, the locking tooth or plate I), riveted to the arm B and securing; it rotatively to the head, the locking-spring 0, provided with stops 0 c and notch c, and riveted to the head on the arm 13, and a spur, a on the head engaging the notch a, substantially as set forth.
